Temperature Controller

DiGi-Sense^® Temperature Controllers (68900-01 Standard & 68900-11 Deluxe)

• Direct plug-in of heating devices
• Accepts up to 8 thermocouple probes (advanced model accepts RTDs and YSI thermistor probes in addition)
• Plain English menus with two-line display simultaneously show measured value and setpoint
• Adjustable over-temperature and loop break cutoff give fail-safe operation
• 2 control modes: on/off or PID
• PID parameters can be entered manually or automatically using the "auto-tune" feature
• Field calibration offset compensates for probe error
• UL approved for Class 2 output circuit
• Meets CE requirements for electromagnetic compatibility
• Deluxe Model features ramp & soak profiles and RS-232 communications for computer control of system parameters, FREE software included

Use our new temperature controllers for a wide variety of temperature control applications. Choose from standard or deluxe models. Both controller models provide excellent control accuracy and power capabilities, making them ideal for pilot process plants, R & D labs or OEM requirements. Use as a bench controller or panel mount with the optional panel mount kit, sold separately.

Both controller models accept; J, K, T, E, N, B, R or S thermocouple types with mini-connectors. Deluxe model also accepts 400 & 700 series thermistor probes with 1/4" phono plug or RTD probes with 3-pin connectors adapters available upon request.

Features - Rear panel output receptacle for direct plug-in of heaters and other devices. Field Calibration - improve system accuracy by entering offset value to correct for individual probe error. View set-up and operational parameters on two line alphanumeric display for easy programming. Temperature Scales - °C, °F, K (Kelvin) or °R (Rankin). Non-volatile memory stores set-up parameters, if power is lost parameters are saved.

Alarms - Fully Programmable; choose from alarms off, manual reset (via front panel push button) or automatic reset. Set either a High, Low, High/Low or Band. All alarms feature adjustable hysteresis and an audible alarm option. Deluxe model includes SPDT alarm relay.

Safety Features - Output power to load device automatically shuts down in the event of a broken sensor or control loop break. Over Temperature Protection shuts down the system if OTP setpoint is exceeded. Output power receptacle is fused separately for added safety.

Standard Controller has a 115/230 VAC, 10A (1150/2300 watts) max heater output. Select from three control modes: on/off, Autotune for standard PID applications or Programmable PID for non-standard PID applications. Front Panel LEDs indicate status of output alarms.

Deluxe Model has all the features of the standard controller plus: higher heater output capacity of 115/230 VAC, 15A (1725/3450 watts) max, program up to nine ramp and soak profiles for more complicated processes, bidirectional RS-232 computer interface with selectable baud rates (300 to 9600), WINDOWS^® software program (system requirements are 386 computer or better, WINDOWS 3.1 or later, EGA, VGA, or compatible monitor). Deluxe model also features an isolated 4-20 mA output, scalable for positive or negative slope, 250 ohm resistor is included for conversion to a 1- 5 V output signal, output connector included.
